ELECTROLYTE FOR PRODUCTION OF IRON-NICKEL ALLOYS Russian patent published in 2019 - IPC C25D3/56 

FIELD: technological processes.

SUBSTANCE: invention relates to electroplating and can be used in machine building for obtaining coatings with iron-nickel alloy on recoverable parts of worn-out parts of machines, in particular, agricultural machines. Electrolyte contains, g/l: iron dichlorated FeCl₂×4H₂O 380–420, nickel chloride NiCl₂×7H₂O 100–150, sulfuric acid H₂SO₄ 0.8–10.0 ml/l, potassium iodide 3–5, hydrochloric acid to pH 0.8–1.0, tetraethylammonium hydrochloride 3–4 g/l, hexamethylene-Ń,Ń,N,N-tetraacetic acid 0.5–3.0, sodium polymethylene-β-naphthalenesulfonate 0.01–0.02 g/l.

EFFECT: high dissipation and coating capacity of the electrolyte, high corrosion resistance and low roughness of the coating, high stability of the electrolyte, wider operating densities of the current and high adhesion of the coating to the base of the steel part.
